Scope

This International Standard specifies the mandatory and optional information to be recorded in any registry of OIDs, using an information model.

It specifies what parts of that information shall be regarded as public, and what parts shall be subject to security and privacy requirements.

In detail, this International Standard:

  • specifies an XML format for the export of the contents of an OID registry, suitable e.g. for import to a different OID registry;
  • references the Object Identifier Resolution System (ORS) which provides a look-up mechanism for information related to an object identifier, with guidance on the use of that facility.

Terms, definitions and abbreviated terms

Terms and definitions

OID registry and OID repository

An OID registry maintains a list of OIDs.

Typically additional information (metadata, such as responsible organizations, a human readable name, a description of the object, and other information that is needed for any meaningful use of the object identified) associated with the OID is stored also. With that, a registry is then a repository at the same time.

Maintaining the list (and associated metadata) happens regardless whether it is an official register for allocations of new OIDs under a given OID arc, or just a copy of information from other registries.

Official OID registries/repositories responsible for allocations of new OIDs under a given OID arc are Registration Authorities.

Registration Authority (RA)

A Registration Authority (RA) is responsible for allocating child arcs to the OID that it manages (issuing authority).

It ensures that an integer is used once among the subsequent arcs (child OIDs). As much as possible, it avoids the same identifier (beginning with a lowercase letter) being used for multiple sub-arcs.

Such information is typically stored in the OID registry/repository but it is important to understand that an OID first need to be officially allocated by an RA before it can be described in an OID repository.

For each child OID, the RA also keeps a record of additional information (like name of a contact person, postal address, telephone and fax numbers, email address, etc.) about the Responsible Authority for that child OID.

A responsible authority for a child OID is formally becoming a RA for that child OID, as it may allocate sub-arcs.

Responsible (Managing) Authority (MA)

A Responsible (Managing) Authority (MA) is used to indicate the person (if known) and organization who is currently in charge of managing the OID.

Once a responsible authority is allocating sub-arcs and registering information on these sub-arcs, it also becomes the Registration Authority for these sub-arcs.

Submitting Authority (SA)

This information is optional and reflects the person or organization that submitted the original OID allocation request.

Relationship to and discussion of definitions from other sources

Current Registrant

In some OID registries, Current Registrants are stored. The definitions from other sources say that the Current Registrant is used to indicate the person (if known) who is currently in charge of managing the OID, allocating sub-arcs and registering information on these sub-arcs.

Discussion: simply managing an OID (for example for a code system) is a Responsible Authority MA. Potentially, a responsible authority may become a Registration Authority RA for a sub-arc if it allocates sub-arcs.

First Registrant

In some OID registries, First Registrants are stored. The definitions from other sources say that the First Registrant is used to indicate the very first person (if known) who was responsible to manage the OID and who created it in the first instance.

Discussion: Suggestion is to distinguish between a Registration Authority RA (person if known, and organization) who issued (= allocated the instance of) an OID and a Submitting Authority SA who submitted the OID allocation request (which may be the same instance). In this sense the First Registrant is the Registration Authority RA.

Note: Due to a comment from the Canadian ISO representatives Registration Authority even could be renamed to Issuing Authority.

First Registration Authority

The first Registration Authority of an OID is the very first person or company to whom the OID was allocated by the RA of the superior OID. According to Rec. ITU-T X.660 | ISO/IEC 9834-1, the first RA can't be changed (if the responsibility is transferred to someone else, the information is recorded in the "Current Registration Authority" section, without changing the "First Registration Authority" section).

Discussion: This is the Registration Authority RA that allocated the OID.

Rec. ITU-T X.660 | ISO/IEC 9834-1

In ITU-T Recommendation X.660 the following definitions are given.

3.6.8 registration authority: An entity such as an organization, a standard or an automated facility that performs registration of one or more types of objects (see also International Registration Authority).
3.6.2 administrative role (of a registration authority): Assigning and making available unambiguous names according to the Recommendation | International Standard defining the procedures for the authority.
3.6.14 technical role (of a registration authority): Recording definitions of the objects to which names are assigned and verifying that these definitions are in accordance with the Recommendation | International Standard defining the form of the definition.

This Technical Standard does not use administrative or technical roles.

Legenda of Tables and Symbols

Class Attribute and Association Tables

The Class Attribute Tables (information model) make use of the following table headline:

Attribute Description DT Card Conf Length

where

DT = datatype conformant to the ISO 21090 datatypes,

Card = cardinality, e.g. 0..1 or 1..* etc.

Conf = conformance, either

  • mandatory which means that the information SHALL be present in every instance of an extract of an OID registry/repository, or
  • required which means that the information SHOULD be provided if there are no privacy reasons for masking that information, or
  • optional when information is optional.

Length = recommended length (as an implementation hint e.g. for data base string lengths etc).

In addition, the Association Tables (information model) make use of the following table headline:

Association Description Class Card Conf

where

Association = the association name to the associated class

Class = the associated class name

Object Identifiers in healthcare

OID (Object Identifiers) are unique identifiers for any kind of objects. They are defined in Rec. ITU-T X.660 | ISO/IEC 9834-1[1] [2]. This identification system for objects and concepts makes reliable electronic information exchange possible. Administration and Registration is regulated by a set of rules (see also ISO/NWIP/TR "Health Informatics – Guidance for maintenance of Object Identifiers OID"[3]).

The precise designation of objects and concepts is a pre-requisite for the standardized exchange of information. A globally unique identifier for each of these concepts will help to ensure international exchangeability of objects within different applications (e.g. healthcare information systems). For example, OIDs are often used within HL7 messages and documents, and Rec. ITU-T X.509 certificates to provide this unique identification.

In the exchange of healthcare information, especially between loosely coupled systems, additional information about the object being identified is generally very beneficial; this is information that is typically not contained in a transaction of data between systems but is reference information about the objects contained in the transaction. There is a minimal set of such information, such as Responsible Organizations, a human readable name, a description of the object, and other such information that is needed for any meaningful use of the objects identified. Since such information may not be locally available to a system examining the communicated objects, it makes sense to have such information available in a standardized form, and accessed by using the OID to identify this information. Such information, referred to as the OID metadata, is the bulk of the information housed in an OID Registry.

Today, due to lack of standardization of the set of metadata (both content and structure), existing OID registries are not compatible. Contents, attributes and rules of the assignment of OIDs of existing registries are incompatible and often dissimilar. Many registries still distribute OIDs in a form only suitable for direct text processing (like spreadsheets) that is error prone and hard to automate. There is a need to store and transfer collections of OIDs and also to keep some registries completely in sync, maintaining the contents and the structure of metadata of each of the registered OIDs e.g. descriptions, comments, versions, links, relations, responsible organizations and persons, etc.

Data exchange can be facilitated by a standardized representation of a required minimum set of metadata as an XML structure together with the associated checks of underlying constraints and business rules. This XML structure for importing and exporting OIDs amongst different registries should be achieved for supporting eHealth applications. In addition, the failure to have a standard for the operations needed to coordinated and synchronize the contents of disparate OID registries leads to confusion and ambiguity for the community that uses eHealth information containing references to objects identified by OIDs.

There are currently at least hundreds of OID registries in active use throughout the world. These are sponsored and operated by disparate entities, ranging from national governments, to individual companies or standards organizations, to individuals in a specialized area or industry. In many cases, more than one of these registries address the same industry segment, and have overlapping content, i.e. specific OIDs exist in both, or worse, different OIDs identifying the same object exist in both. This distributed set of disparate registries servicing a particular industry (specifically Healthcare IT) has led to awkward and error prone searching processes. To get information about existing OIDs, a search within all existing registries is needed, for example to avoid duplicate assignment of multiple OIDs to one and the same concept. In order to standardize the activities to synchronise all existing OID registries and to ensure further interoperability it is essential to have a defined exchange format and business rules for maintenance of the OID registries that must cooperate in a particular industry.

Some OID registries are operated by essentially volunteer organizations, such as Standards Bodies. The burden of administrative tasks is such that multiple individuals, often in different geographical locations, must participate to share the workload. Thus in addition to distributed Registry instances, administrative functions need to also be distributed, both on single and potentially across multiple Registries. There is a need for the standardization of a minimum set of administrative access and operational functions such that developers of Registries can deploy standard mechanisms to streamline and increase accuracy and productivity of these maintenance operations.

This Technical Standard describes a generic exchange format that will cover the minimal set of metadata and associated rules for OIDs of existing registries. It specifies principles and processes that should be explored/implemented by developers and data administrators of OID registries and their applicant bodies. The primary target group for this document are those establishing OID registries and those (industry, government bodies) using the services maintained by such organizations.

Additional descriptions

A general description of the registration procedures for various parts of the object identifier tree, by reference to other specifications and links to other documents is given in ISO 13581 - Health informatics - Guidance for maintenance of object identifiers, OID - Technical Report.

In informative Annex A, a description possible of sub trees reflecting OID categories for e-health related OIDs is given.

Informative Annex B specifies an Object Identifier Resolution System (ORS) for e-health related OIDs based on RESTful Web Services.

Related work

This work is related to discussions about OID in the work programme of TC 215 WG3, HL7, ISO/IEC JTC 1/SC 6, ITU-T SG 17 and other organizations dealing with OIDs and OID registries.

Approach

Following an extensive analysis of the currently available international OID register for health care systems, a basic data set and a corresponding XML representation as an exchange format need to be created for registering and exchanging OID-related data. To collect the very basic requirements to such a format an analysis of several registers (e.g. HL7 International[4] register and several European registers[5][6] was performed so far in 2009 (see Table 1). The analysis included the contents, attributes and even the rules of the assignment of OID.

Only a few of the registers specified an (XML-) exchange format. Due to lack of a common understanding of OID registry requirements, data fields must be mapped (manually) when OID information needed to be exchanged.

Information model

In order to exchange OID and their metadata between different registries and applications the following additional data items beyond the OID itself need to be taken under consideration (see also [7] [8]):

  • descriptions
  • status information
  • categorization
  • time information
  • comments
  • versions
  • links
  • relationships to other OIDs and external sources
  • registering and responsible organizations
  • associated persons.

An information model with all classes, attributes and their properties aiming on a common understanding of the requirements of an OID registry has been created (Figure 1).

OID Registry Model (Draft)

XML exchange format

Data exchange can be facilitated by a standardized representation of the complete set of information as an XML structure together with the associated checks of underlying constraints and business rules. This XML structure for importing and exporting OID amongst different registries and other healthcare applications is aiming on the availability of reliable information about OIDs.

The following sections summarise and explain classes and their attributes.

  • identifiers of an arc are required to commence with a lowercase letter, and to contain only letters, digits, and hyphens.
  • the last characters shall not be a hyphen
  • there shall be no two consecutive hyphens in the name

Example

nl

category

The type/category of the OID; enumeration, values see value set OIDCategory.

There are actually two main types of OIDs: leafs (id of an object), and nodes representing an ontological branch.

The types of node OID may be

  • a registration authority (RA) or
  • a structure for the management of OIDs.

The proposal for sub categories of leaf OIDs are

  • identifiers of an instance of an object (for example a person)
  • namespace identifiers (for example code systems, value sets)

status

Status of the OID. This is an enumeration, for values see value set OIDstatus

creationDate

The creationDate is used to describe when the OID was first registered. It is not the date when the OID description is submitted to the OID repository. The creationDate, once set, never changes.

realm

Code of country or "UV" for universal. This is an enumeration, for values see value set CountryCodes.

description

This element contains a free text description of the OID ("what is the OID?"). The text typically contains an explanation but also can contain:

  • explicit versioning aspects
  • licensing information
  • Intellectual Property rights information
  • trademarks.

The datatype ED allows for a thumbnail child element. A thumbnail may be populated describing a short description of the OID (sometimes referred to as identifier name).

Example:

<description language="en-US" value="this is plain text as a long description">
   <thumbnail value="short text"/>

HL7 International makes a suggestion[13] for a structure of object types

  • .1 HL7 registered internal objects (other than organizational bodies)
  • .2 HL7 organizational bodies and groups
  • .3 External (not HL7) group functioning as a Registration Authority
  • .4 Registered externally maintained identifier systems and namespaces
  • .5 HL7 Internal Code Systems
  • .6 Registered external coding systems
  • .7 HL7 published document artifacts
  • .9 HL7 Registered conformance profiles
  • .10 HL7 Registered Templates
  • .11 HL7 defined and registered Value Sets
  • .12 HL7 Version 2.x tables
  • .13 Externally authored and curated Value Sets
  • .14 Assignment Ontology node
  • .15 Small code sets externally defined
  • .17 Non-specified type
  • .18 HL7 Version 2.8 Coding Systems
  • .19 HL7 Examples

From a policy perspective it is common practice in several healthcare related (European) OID registries [14] [15] [16] and makes sense to distinguish at least between the following types of OIDs:

  • .3 organizational bodies and groups
  • .4 identifier systems
  • .5 code systems
  • .7 documents
  • .9 conformance profiles
  • .10 templates
  • .11 value sets
  • .19 examples
  • .99 experimental

Data types

ISO data types[17] are used for the XML representation of data. In some cases additional flavors or constraints are defined.

The following section gives examples and describes the restrictions / contraints on the generic specification.

Address AD

Example:

<addr use="HP">
 <part type="STR" value="Windsteiner Weg"/>
 <part type="BNR" value="54a"/>
 <part type="CNT" code="DEU" codeSystem=" 1.0.3166.1.2" value="D"/>
 <part type="ZIP" value="14165"/>
 <part type="CTY" value="Berlin"/>
</addr>

Coded Simple CS

A coded attribute. The attribute is always bound to a specific code system mentioned in the code systems section.

Example:

<statusCode code="OBO"/>

Encapsulated Data ED

</validTime>

String ST

A character string

Example:

  <description value="I am a piece of text"/>

Object Identifier (dot notation) ST.OID

This is actually a character string (ST) with a certain pattern.

The pattern is:

Example:

<oid value="1.2.3.4.5.0.6.7.8.9"/>

Object Identifier (asn1 notation) ST.ASN1

This is actually a character string (ST) with a certain pattern.

The pattern is:

\{?\s*(([a-z][a-zA-Z0-9\-]*\s*((\s*(0|[1-9][0-9]*)\s*\))?|(0|[1-9][0-9]*))\s*){2,}\s*\}?

Object Identifier (iri notation) ST.IRI

Basic interactions between OID registries

A set of basic interactions is developed and documented in order to facilitate the exchange of OID-related information between registries. This will include at least the following transactions:

  • Share OID list
  • Retrieve OID list

Use Cases

A list of OID Registry Use Cases has been defined in order to drive metadata model requirements, and functional requirements for Registry interoperability.

U1: OID Creation where the registry owner is the RA

  • Creation of a new OID in the standard ontological structure
  • Creation of a new OID in a sub-structure

U2: OID Registration

  • Registration where the registry owner created the OID
  • Registration of an OID created elsewhere

U3: OID Withdrawal/Replacement

  • Withdraw an OID created in error with no replacement
  • Withdraw an OID created in error with specified replacement
  • Withdraw an OID registered in error with no replacement
  • Withdraw an OID registered in error with specified replacement
  • Withdraw an OID that is found to be a duplicate, with original specified

U4: OID Metadata Update/Editing

  • Permissions model
  • Distributed effort model
  • Proxies for Editors

U5: OID Information Publication

  • Web presence
  • Internet-accessible API (Web service presence)
  • Full registry output to machine-readable form
  • Full registry output to human-readable form
  • Partial registry output to machine-readable form
  • Partial registry output to human-readable form

U6: OID Information Request

  • Search for the OID of an object
  • Search for the object identified by an OID
  • Search for a list of kinds of OIDs
  • Search for a list of OID based on various sub-criteria, with and without wildcards
    • Those registered by a particular entity
    • Those associated with a type of information object
    • Those associated with implementation guides
    • Those registered during some time period
    • etc.

Annex A

Annex A is a specific description for the registration procedures for e-health related OIDs, and includes a specification of those parts of the OID tree that are known to be used for national and for international e-health applications.

Object Identifier Resolution System (ORS)

Simple mechanisms should be provided in order to retrieve lists of OIDs from a registry, details of a particular OID or an extract of the entire OID registry. Various formats should be supported like HTML and the original XML format.

The suggested calls should be implemented as RESTful Web Services and their parameters are stated as follows.

Name RESTful Web Service Description Parameters
OIDIndex retrieves an index of all OIDs in the OID registry in HTML format

format (default, fixed): html

id (optional): an OID

language (optional): language

http://oid.server.org/OIDIndex

gets an HTML table of all OIDs in the registry with links to the details for each OID

http://oid.server.org/OIDIndex?id=1.0.3166.1.2.2

gets an HTML table of OID 1.0.3166.1.2.2 with links to the details for this OID

http://oid.server.org/OIDIndex?id=1.0.3166.1.2.2&language=de-DE

gets an HTML table of OID 1.0.3166.1.2.2 with links to the details for this OID in the German language

RetrieveOID retrieves a particular OID in the OID registry

id (required): an OID

format (optional): html or xml

language (optional): language

http://oid.server.org/RetrieveOID?id=1.0.3166.1.2.2&format=html

gets details of OID 1.0.3166.1.2.2 in HTML format

http://oid.server.org/RetrieveOID?id=1.0.3166.1.2.2&format=html&language=de-DE

gets details of OID 1.0.3166.1.2.2 in HTML format in the German language

http://oid.server.org/RetrieveOID?id=1.0.3166.1.2.2&format=xml

gets details of OID 1.0.3166.1.2.2 in XML format

GetOIDRegistry gets the entire content of the OID registry in XML format

format (default, fixed): xml

http://oid.server.org/GetOIDRegistry

gets the entire content of the OID registry in XML format
